This invention relates to an advertising demonstrator and moreparticularly to a device for demonstration by immersion.

It is the object of the present invention to provide an advertisingdevice for demonstrating the sealing properties of grave vaults and thelike in which the scaling is by the air-bell type. More specifically, itis the object of the present invention to provide a miniature casket andvault therefor and a device for permitting the casket and vault to bereadily immersed with very little pressure and which device Will returnthe casket and vault, or similar objects, to their original position.

Other features have to do with details of the immersion unit and detailsof structure as will be more clearly brought out in the specificationand claims.

In the drawing:

Fig. 1 is a vertical sectional view of one form of my demonstratorwherein the object and cover are shown in their normal position, a floatbeing used to just counter-balance the weight of the demonstrator parts.

Fig. 2 is a view similar to Fig. 1 showing the object and cover beingimmersed by a slight pressure and showing the absence of liquid beneaththe cover, a modified form of counter-weighting mechanism being used. 3Fig. 3 is a view similar to Figs. 1 and 2 but showing the article andcover being returned to normal position and the cover being removed tofurther illustrate the demonstration, a. still further modified form ofcounter-weighting mechanism being illustrated in this figure.

The main purpose of my device is an advertising demonstration of airsealed objects by immersion, and in the preferred form of my advertisingdevice I utilize for the demonstration a 40 miniature grave vault cover2 and a miniature casket 3, said cover, or at least a portion thereof,preferably being of glass. Normally the cover 2 and object 3 are mountedon a base t which base is carried by a support or guide member 5.

45 The guide member 5 is adapted to be lowered within a tank 6 carryinga given amount of liquid. A demonstrating cabinet is generallyillustrated as at l and the top of this cabinet is provided with anopening 8 for the reception of the 50 cover 2. Depending from the top ofthe cabinet I is a seat 9 against which the support or guide 5 isadapted to contact.

The weight of the cover 2, object 3 and the guide or support 5 iscounterbalanced in some manner so that the cover 2 and object 3 arenormally held in the position shown in Fig, 1; however, thiscounterbalancing is just SllffiClGl'lt to maintain this normal positionso as to make it possible to readily move the cover 2 downwardly toimmerse the same. This shows the prospect that the cover is not held upby a very strong force. In Fig. 1 I have shown a float It sufficient tojust counterbalance the weight of the other parts. A drain plug I l isprovided for the tank 6 and an overflow pin [2 is so positioned as totake care of the overflow at the time of immersion in the event too muchwater is originally placed in the tank.

Fig. 2 illustrates the manner in which the support or guide, the coverand the object are immersed, very little pressure being required toimmerse the object and the cover and the operator seeing that the coveris immersed and also that the interior thereof remains dry. In thisfigure I have illustrated how counterbalancing may be obtained by theuse of a pulley l3 or a spring M. In the preferred form of the device,the cover and object will return to their original position on their ownpower, or on the power created in making the downward stroke. Thebalancing means, whether the float or the weights, may be maderelatively stronger or heavier to obtain a quicker and more positivereturn of the parts to normal position. a

The cover 2 and the article 3 are loosely positioned on the base member4 and in Fig. 3 I have illustrated how the cover and article can beremoved to further illustrate the demonstration and to show the absenceof liquid or moisture beneath the cover. In Fig. 3 I have alsoillustrated modified forms of balancing means which may be tensionspring means 55, compression spring means IE, or weights and levers ll,each of which may be used separately or in combination to hold the cover2 and article 3 in their normal exposed position.

What I claim is:

1. An advertising demonstrator device comprising an enclosure having anopening in the top wall, a tank of liquid depending beneath the opening,a base member slidable in said liquid tank, a miniature demonstratingcover having air tight side and top walls and an open bottom and adaptedto rest on the top of said base member, said opening in the enclosurebeing of a size to permit said cover to pass therethrough, andcounterbalancing means operably connected with said base member to movesaid base member and cover to the top of said tank after immersion andto maintain the cover in exposed position above the liquid in the tank.

2. An advertising demonstrating device comprising an enclosure having anopening in the top wall, a tank of liquid depending beneath the opening,a support and guide member forming a movable base member whereby thebase member is movable into said liquid tank, said base member beingformed to receive a miniature box-like demonstrating cover having anopen bottom, means depending from the top of the enclosure forming aseat against which the support normally contacts, and counterbalancingmeans operably connected with said base member to urge the base memberupward thereby normally maintaining the cover in exposed position abovethe liquid in the tank.

3. An advertising demonstrating device comprising an enclosure having anopening in the top portion, a tank of liquid depending beneath theopening, a support and guide member forming a base member for receivinga miniature cover to be demonstrated, said cover being box-like in shapeand having an open bottom adapted to rest on said base, said base andcover being movable whereby they may be manually immersed in said tank,and counterbalancing means operably connected with said base member andnormally operable to maintain said cover in exposed position above theliquid in the tank.

4. An advertising demonstrating device comprising an enclosure having anopening in the top portion thereof, a tank of liquid depending beneaththe opening, a perforate support and guide member forming a base memberfor receiving a miniature cover to be demonstrated, said cover being ofhollow rectangular shape with an open bottom, said opening being ofsufficient size to permit the cover to pass therethrough, said perforatesupport and guide member being movably mounted whereby the base memberand cover may be easily immersed by hand, and counterbalancing meansoperably connected with said base member to maintain the cover normallyin exposed position above the top of the enclosure and operable toreturn said cover to exposed position subsequent to manual immersion.

5. An advertising demonstrating device comprising a liquid container, aperforate support extending into said liquid for receiving a miniaturecover to be demonstrated, counterbalancing means operably connected tosaid support and of such strength as to counterbalance the weight of themeans being demonstrated and the support whereby said means is normallypositioned above the liquid, said counterbalancing means cooperatingwith said support to return the support and cover to exposed positionafter manual immersion.

6. An advertising demonstrating device comprising a liquid container, asupport for receiving a miniature glass cover and enclosed article to bedemonstrated, counterbalancing means operably connected with saidsupport and of such strength as to counterbalance the weight of themeans being demonstrated and the support whereby said means is normallypositioned above the liquid, said counterbalancing means cooperatingwith the support whereby to return the support and cover to exposedposition after manual immersion.
